I previously had an ex cranial implant and because I could feel the implant I developed mad phobias of insects, mainly because when it was turned up it felt like a wasp in my head. I could rationalize it but couldn’t help the fear. Since the intercranial implant this has gone away as there are no nerves in the brain (the 12 hour operation I was awake for).
I don’t feel anything until I turn the device up and for a few seconds I feel like that character in the film Lucy, then back to normal. When the device stops working I have to go into hospital and they effectively jumpstart me by sending the signal around the opposite direction. This starts tricking the brain into stopping the pain from my cluster headache’s.
The amazing thing is that since the implant I haven’t had to take a single piece of medication and I used to have bags of it. The device is also used to treat Tourette’s and Parkinson’s.
